ROUGH-ROUNDING AND CHANNELING MACHINE.

SPECIFICATION forming part of Letters latent No. 463,967, dated November24, 1891.

Application filed June 24, 1891. Serial No. 397,302. (No model.)

To all whom it may concern.-

Be it known that I, HENRY BRIGGS, a citizen of the United States, and aresident of the city, county, and State of New York, have inventedcertain new and useful Improvements in Rough-Rounding and ChannelingMachines, of which the following is a specification.

My invention relates to improvements in machinery to rough-round andchannel boot or shoe soles while upon the shoe and with the last in orout of the shoe. I attain this object by the device shown in theaccompanying drawings, in which Figure 1 shows a front elevation of mymar5 chine as in operation, with the feed-clamp 1 forward (toward A) andlocked and the fourmotion drop-feed 45 also forward toward A; Fig. 2, adetail of throat-plate and gage 15,feedclamp 1, and four-motiondrop-feed 45 in front elevation, the solid lines showing themlocked incontact, as in Fig. 1, the two latter being forward, (toward A,) thedotted lines showing the two latter back (toward B) with the fourmotiondrop feed 45 down; Fig. 3, a vertical 2 5 transverse View ofthroat-plate and gage 15,

C D looking from B toward A of Fig. 1; Fig. 4, an end view of Fig. 1looking from B toward A of Fig. 1; Fig. 5, a vertical transverse sectionon line E F of Fig. 1 looking from A toward B of Fig. 1; Fig. 6, an endView of Fig. 1 looking from A toward B of Fig. l, omitting parts 15, 20,24, 44, 46, and at; Fig. 7, a vertical transverse section of the forepart of a shoe while being rough-rounded and chan- 3 5 neled in thismachine, looking fromA toward B of Fig. 1; Fig. 8, a detail ofthroat-plate and gage 15, sliding pin 1O6,'feed-c la1np 1, andfour-motion drop-feed in front elevation, the solid lines showing thefeed-clamp 1 drawn back toward B, the four-motion drop-feed 45 also downand back, (toward B,) the dotted lines showing the two latter fedforward toward A, with the four-motion drop-feed 45 also up. 45 Similarletters and figures denote similar parts throughout-the several views.

This machine is designed to rough-round and channel boot or shoe soleswhile upon the shoe, and with the last either in or out of the shoe,While the work operated upon is being automaticallyfed through themachine.

In previous machines of this class the feed movement has beendefectivein its operation in some parts of the process. For instance,when the sole operated on has no material in places outside of the cutmade by the edge trimming or oscillating cutting-blade the four-motionfeed-blade or feed-awl heretofore used will not have any material toenter, and consequently will not be able to feed the sole 6o operatedupon forward or against the edgetrimming or oscillating cutting-bladeand channeling-knife, necessitating this feeding being performed byhand. By my invention this mechanical defect is overcome and the shoeand sole are fed forward automatically to the channeling-knife 72 andedge-trimmer or oscillating cutting-blade 89 by a positive feedmotion 45and feed-clamp 1. The principal objects to be attained in this part ofthe process of the manufacture of boots or shoes are that the edge ofthe sole operated upon shall be rough-rounded to an equal and uniformwidth from the inseam, and that the channel shall be out at any varieddistance 75 desired from the rough-rounded edge of the sole, as in theshank the channel is required to be at a greater distance from theroughrounded edge than in the fore part of the sole.

My invention consists of a frame carrying a main rotating shaft a,havingupon it hubs or cams b 0 (Z to correctly actuate the various parts ofthe machine to feed, roughround, and channel the soles of boots or shoeswhile upon the boot or shoe and with the last in or out of the boot orshoe. A vertically and horizontally adjustable channeling-knife 7 2,having a vibratory motion, is supported and operated by the knife holderor carriage 73, mounted on and supported by 0 the upper part of thevibrating arm 86. This channeling-knife 72 and its holder or carriage 73and vibrating arm 86 are vertical, or nearly so, and supported by thepivot'or fulcrum 77 as a center. This vibratingchanneling-knife 5 "2 andits holder or carriage 7 3 are mounted on the vibrating arm 86 and arecapable of being raised and lowered by the screw-thread andadjusting-screw 76 to cut the channel in the sole to the depth required.The vibrating arm 86 is mounted on the slide-block 78 by its pivot orfulcrum 77 extending into the slide-block 78, which extends through thegrooved block 79, permitting lateral adjustment of the slide-block 78and channelingknife 72 to the required distance from the edge of thesole to be channeled. The groove for the slide-block 78 is cut in therigid part or standard 116 of the frame of the machine. The slide-block78 carries a stud 92, which is embraced by the slot 91 in thehand-lever93, pivoted at 94 to a rigid part of the machine, so that theslide-block 78, vibrating arm 86, knife holder or carriage 73, andchannelingknife 72 maybe moved laterally by the handlever 93.

The slide-block 78 is a T-shaped piece, the arm 79 containing twostop-screws 96 and 97, screw 96 screwing through arm 79 and stoppingagainst arm 08 of plate 95, the other screw 97 passing through arm 79 ofslide-block 78 and screwing into arm 98 of plate 95 to regulate thelateral adjustment of the slideblock 7 S, vibrating arm 86, knife holderor carriage 73, and vibrating channelingknife 72.

A bracket 80, attached to the lower part of the frame of the machine,supports a rockshaft 105, pivoted in two lugs 81 and 82 of the bracket80. One arm 115 of this rockshaft 93 carries a cam-roller 85, gearedinto the groove 84 of the cam-wheel b. The other end 118 of therockshaft 105 carries a swivelblock 126, geared into a slot 107 in thevibrating arm 86, vibrating this arm 86 on its fulcrum or pivot 77.

The part of my machine intended for roughrounding the sole at the sametime that the channel is being out consists of the oscillatingcutting-blade 89, having its cutting-edge parallel to its axis ofoscillation and passing through the long slot forming the throat of thefour-motion drop-feed 45, through the work, and through the throat orslot of the throatplate and gage 15, and operating,in connection withthe edge of the throat of the throat-plate and gage 15, to form ascissorcut, separating or rough-rounding the sole as it is fed forward(from B toward A) bythe fou r-motion drop-feed 45 and feed-clamp 1. Thisthroat-plate and gage 15 and feed-clamp 1 are connected by a pin orpivot 106, projecting from the side of the feed-clamp 1 and sliding in aslot in the throat-plate and gage 15, which permits a lateral movementalso of the feed-clamp 1. My oscillating cutting-blade 89 is attached toa carrying-segment s, which is mounted to turn about the bolt 15, thehead of the bolt acting against one side of the segment 5. This segment5 and oscillating cutting-blade 89 are oscillated by the rack 21 at theend of a lever 22, pivoted at 23, a pin or roller 2;

entering a cam-groove 25 in the disk or cam c. The four-motion drop-feed15 is attached to one arm 107 of a bell-crank pivoted at 108 to theupright portion of the feed-slide 50, the other end 109 of thebell-crank having a roller 110, bearing against the periphery of the cam0, having a depression 111 to allow the feed end to drop at the propertime. The lower portion 50 of the feed-slide works in guideways g,attached to a rigid part of the frame of the machine, and has a stud h,geared in a slot in a lever 'i, one end of said lever i oscillating on apivot or fulcrum 7, attached to a rigid part of the machine, the otherend carrying a cam-roller e, gearedinto the groove 6 in the cam-wheel d.The upright arm 119 of the feed-slide 50 carries the swing-piece orlock-segment 4:4, pivoted at 48. Th is lock-segment 44 carries on itsupper side the hand-lever 46 and feed-clamp 1. The throat-plate and gage15 is pivoted at t on the rigid standard 116. The lock-segment at has onits upper end teeth 18, which gear into the pinion u, pivoted at w onthe rigid part or standard 20, through which the pivot passes, andcarries on its other end the ratchetwheel 24. The throat-plate and gageand feed-clamp 1 are pressed down on the work by a spring as, acting atone end against the hand-lever 46 and at the other end against thestandard 20. The throat-plate and gage 15 and feed-clamp 1 act incombination as the gage for the work operated on, as well as forming aclamp with the four-motion dropfeed 4:5. The lock consists of theratchetwheel 24, the two pawls 47 and 48, their pressure-springs a and yto operate in connection with them, and the cam-lever v, pivoted at 2 onthe rigid part of the frame of the machine, this cam-lever t having aroll 13 geared into the cam-wheel (Z.

The work-support consists of two adj ustable rests 113 and 114, havingslotted uprights, which may be adjusted to accommodate any style ofround or flat boot or shoe sole, as different styles of lasts vary intheir shape of bottom. The rest 113 has a flat surface on its upper end,which comes in contact with and supports the solo. The distance whichthe vibrating channeling-knife 72 projects above this flat surface givesthe depth of channel required. The other work-support 114 has a rollerat its upper end, the height of which may be adjusted to suit the pitchof any shape of sole operated upon.

In Figs. 1, 2, 3, 4, 5, 0, and 7 the solid lines show the position ofthe parts of the machine as in operation with the four-motion dropfeedup and forward, (toward A,) the throatplate and gage 15 and feed-clamp 1also looked and forward, (toward A,) the oscillating cutting-blade 89being up at the end of its stroke. The four motion drop -feed 45 thenmoves down and backward, (toward 13,) the lock of the feed-clamp 1 andthroat-plate and gage 15 unlocks, and the feed-clamp lnext movesbackward, (toward B.) The oscillating cuttingblade 89 now drops. At thesame timethechanneling-knife 7 2 and its hand-lever 93 are in positionfor the channeling-knife 72 to commence cutting the channel at theproper distance from the edge of the sole in the shank, the dotted linesshowing the position of the hand-lever 93 when adjusting thechannelingknife 72 to cut the channel in the fore part of the sole.

The operation of this machine is as follows: To insert the work, thehand-lever 46 is pressed back (toward D) to the position shown by thedotted lines, thus raising the feedclamp 1 and throat-plate and gage 15,permitting the work to be inserted between the worksupports 113 and 114and the throatplate and gage 15 and feed-clamp 1 until the inseam isagainst the edge of the two latter parts, the bottom of the sole restingon the guards or work supports 113 and 114. The hand-lever 46 is thenreleased and forced by the spring 00 toward the solid lines, (toward 0,)pressing the feed-clamp 1 and the throatplate and gage 15 against theupper side of the sole of the boot or shoe operated on. The machine isnow put in motion, the lock of the clamp-feed 1 and throat-plate andgage 15 now looks, and the four-motion drop-feed 45 now rises, clampingthe work. The four-motion drop-feed 45 and feed-clamp 1 are next movedforward (from B toward A) by the feed-motion 50, carrying the workclamped between them from B toward A. The oscillating cuttingblade 89now moves upward through the fourmotion drop-feed 45, and the sole isoperated on, the throat-plate and gage 15 separating or rough-roundingthe edge of the sole. The lock of the feed-clamp 1 and throat-plate andgage 15 next unlocks, the four-motion dropfeed 45 drops down, and itsbackward movement from Atoward B takes place, while the throat-plate andgage 15 with the work remain stationary. Next the oscillatingcutting-blade 89 drops down, leaving the machine in the position it wasin when the work was inserted. The spring 00 presses the hand-lever 46,so as to keep the feed-clamp 1 and throat-plate and guide 15 presseddown on the upper part of the sole and automatically adjusts them forany variation in the thickness of the sole operated on.

WVhen the machine is started, the vibrating channeling-knife 72 is alsoput in motion, actuated by the cam-wheel b, and continues to operatewhile the four-motion drop-feed 45, feed-clam p 1, and oscillatingcutting-blade 89 are in action, the distance of the channel from theedge of the sole being regulated by moving the hand-lever 93. By arepetition of these motions the boot or shoe sole is rough rounded andchanneled. When the operation is finished on the sole operated upon, themachine is stopped in the position described when ready to insert thework. The hand-lever 46 is then pressed back, (toward D,) raising thefeed-clamp 1 and throat-plate andguide 15, releasing the sole, which isthen removed from the machine, which is now ready for the insertion ofthe next sole to be operated upon.

If preferred, the pin or pivot 106 may be attached to the throat-plateand gage 15, and

pass into a slot in the feed-clamp 1, or it may be a loose pin or pivotorbolt passing through both parts 15 and 1, of sufficient length topermit the lateral movement of the feed-clamp 1, as previouslydescribed. I

In Fig. 3 at 89 I have shown a side view of my oscillating cutting-bladegrooved on the upper side, an end View showing it, as at 89', atthe endof the face and sides for the purpose of removing the chips or wastematerial in sections in place of in a continuous strip as removed by aflat-edged oscillating cutting-blade which may also be used in thismachine; but I prefer to use the grooved os- 2.
